I remember that. I was around 15. I have another version on VHS where they show Mitch talking about Tysons Diet Pepsi commercial with Robin Givens. They would Show Mitch talking, then show a little clip of the commercial. A little part went like this:

Mitch: (moching Tyson pretending he's holding a can up to his face) (in a gay voice) "I like my diet Pepsi" (normal voice)"Like a little sissy" "She...she... slapped she...she hit him with a towel on the butt"

Commercial: (Robin smacks Tyson on the butt with a towel and says) "Lets get the lead out, champ" (Tyson) "Yes dear"
